Hi,
Firstly thanks!
I think this message appeared due to improper placing of some parts by the program itself (bugs). If I remember correctly, some M motors are missing and some minor other parts.
Good luck building!
If you have any further questions, feel free to ask🙂.

Hmmm, motors are there (4 pices), it looks like there are missing whole staff around gear change. There is “line of gears” on the top, but for example worm is missing. I tried to build this model and gear change doesn’t work.😦

Just one note. For lot of people there will be really helpfull to create part list (bricklink format is the bes I think). It is just idea, please understeand, that I really like your work.🙂

Excellent job!
I just have one question or rather one request. Would you happen to have the actual Lego part numbers for the parts list? Or can you just enter the name on the Lego website and they will come up.
Thanks again!

Amazing use of suspension torsion Yoraish. Thank you for sharing the idea.

I have a question about tire speed. Looking at the LDD file, the gear ratio for the rear tires: 12/24=0,5; whereas the front tires: 12/20=0,6. So the rear tires rotate slower than the front tires. If motor RPM is 220, then the rear and front RPMs are: 110 and 132 RPM or 1.8 and 2.2 RPS.

In loose dirt, and with the torsion suspension twisting and buckling, the speed difference may actually help propel the car in uneven terrain.
